Along the way, I’ll show you a few gotchas and common errors in the installation and usage procedure. So, I decided to write down the steps of compiling and installing VMAF, FFmpeg, and computing VMAF with FFmpeg.

no such filter libvmaf when trying to use VMAF with FFmpeg.Īnd the list simply goes on.

I see these questions often on Stackoverflow and similar websites – But, installing and using them appears to be difficult for a large number of users. It’s become very popular as it succeeds (not fully) at automating subjective quality testing that usually requires humans to watch and score videos.įFmpeg and Netflix’s VMAF are now part of every video processing and compression engineer’s toolbox. VMAF from Netflix stands for Video Multi-method Assessment Fusion, and it is a video quality metric that combines human vision modeling with machine learning.

In this tutorial, we will see how to compile and install FFmpeg with VMAF support using libvmaf and then we shall see how to compute or calculate the VMAF score between two videos using FFmpeg with VMAF support enabled.įFmpeg has always been at the top of everyone’s mind when it came to open source video compression software and is best described by Wikipedia asįFmpeg is a free and open-source project consisting of a vast software suite of libraries and programs for handling video, audio, and other multimedia files and streams.

D = Supports direct rendering method 1 V. You can also see the encoders and decoders for each codec. Looking at two popular codecs returned, h264 has DEV.LS whilst h265 has DEV.L meaning h265 is missing Lossless compression ability (In this version). hevc H.265 / HEVC (High Efficiency Video Coding) (decoders: hevc hevc_qsv hevc_cuvid ) (encoders: libx265 nvenc_hevc hevc_amf hevc_nvenc hevc_qsv )

Think putting many frames and audio together and playing them back or when you skip ahead providing the right data. A codec is the logic to encoding or decoding a media stream, there are many different types with popular ones being H.264, HEVC ( H.265) and MPEG-4.Ĭodecs are different to containers like MP4, MKV and MOV because a codec manages the bitrate, resolution and frames whilst the container organizes and returns the data as sequence.
